When the Illinois clock runs out
The deadline runs from the end of the tenancy, not from when you get round to inspecting. On Illinois's 45-day rule, these are the dates you would be working to:
| Tenant moves out | Statement and refund due by |
|---|---|
| January 31, 2026 | March 17, 2026 |
| April 15, 2026 | May 30, 2026 |
| July 31, 2026 | September 14, 2026 |
| November 30, 2026 | January 14, 2027 |
Does Illinois require an itemized statement?
Yes — Illinois requires an itemized written statement of any deductions rather than a lump sum, under 765 ILCS 710. Each charge needs to stand on its own: what was damaged, and what it cost to put right.
What you can actually charge for
Illinois statute sets the deadline and the paperwork; it does not publish a table of what a worn carpet is worth. The defensible method — charging only the useful life the tenant used up early, and excluding normal wear — is the same in every state, and is explained on the calculator, which builds the itemized statement and puts the Illinois deadline on it.
